1. The Debian Project Sam Hocevar (sam@zoy.org) Debian Project Leader 2007-2008 December 8th, 2007 FOSS.IN/07 – Bangalore, India

2. overview 1000+ developers volunteers worldwide an operating system free (beer), free (speech), cross-platform comprehensive (18 000 packages) an infrastructure communication, updates...

3. plan a bit of history Unix, GNU and Linux Debian derivatives organisation and management the social contract, the DFSGs the packages, the infrastructure the developers Debian and Ubuntu Debian and you

4. history

5. (1) – Unix 50s-60s: MULTICS, C, Unix 70s: the Unix philosophy small tools, everything is a file the first BSDs 80s: Unix declinations Xenix, SunOS, HP-UX, AIX, Minix... 1984: the GNU project 1991: Linux 1992: the first distributions

6. (2) - Debian 1993: Ian Murdock starts the project a few hackers release Debian 0.01 GNU sponsors Debian 1995: the dpkg and dselect tools 1996: Debian 1.1 1998: Debian 2.0 (1 500 packages) 2002: Debian 3.0 (9 000 packages) 2007: Debian 4.0 (18 000 packages)

7. (3) – derivatives 2001: LindowsOS Windows emulation, Click’N’Run 2003: Knoppix live CD hardware autodetection 2004: Ubuntu “Linux for human beings” 2007: more than 50 active derivatives education, games, health, multimedia...

8. (4) Debian today the distribution 18,000 packages 11 architectures (more to come: SH4) 2 kernels: Linux and Hurd (more to come: kFreeBSD, hopefully OpenSolaris) the #1 embedded Linux distribution (2007 linuxdevices.com survey) more and more vendor support HP now officially supports Debian Asus Eee PC, Nokia Internet tablets...

9. organisation and workings

10. (1) – the social contract Debian will remain 100% free the “Debian Free Software Guidelines” (DFSG) we will give back to the community we will not hide problems our priorities: our users free software

11. (2) – structure SPI legal and financial structure OpenOffice.org, PostgreSQL... the Debian constitution decision-making amongst developers leader, secretary, technical committee... in practice team rules are much looser (QA, security, release) non-official contributors

12. (3) – packages a package (.deb ) is: an element of software program, library, documentation, typographic font, dictionary word list... easy to install integrates perfectly with the rest of the system free software can be modified can be redistributed

13. (4) – source packages a source package contains: the original source code from the Internet or directly from Debian control information description, licence, menu... build instructions patches system integration bugfixes, improvements

14. (5) – the FTP archive, the buildds, the BTS the FTP archive every package and source package hundreds of mirrors worldwide the “buildds” automated package builds for all architectures the Bug Tracking Sytem (BTS) links users, DDs and sometimes upstream developers reportbug and reportbug-ng tools

15. (6) – the developers’ work maintain their packages test, fix, update communicate with users and upstream work for the project infrastructure tools ( dpkg, apt-get, debian-installer ) comunicate about Debian other themes (standards, legislation...)

16. Debian and Ubuntu

17. (1) the development cycles Debian: a development cycle packages sent to “unstable” transitions to “testing” Debian: a release cycle release goals development done in “unstable” “testing” becomes the new “stable” Ubuntu: a main release cycle synchronisation with Debian unstable development, tests... and release

18. (2) which one should you use? beginners and power users Ubuntu is “sexier” (for now) Debian is more complete watch the communities developers use both! virtualisation ( Xen, KVM ) emulation ( qemu ) confined area ( chroot )

19. (3) Ubuntu’s influence on Debian the positive huge visibility quality increases and various contributions in many areas the, er, not so positive focus switch fewer competent developers fewer users

20. (4) what can Debian do? observe Ubuntu better find more developers encourage direct contributions to Debian instead of waiting for backports encourage creation of communities that means we need you

21. Debian and you

22. (1) contribute help or join a Debian packaging team http://alioth.debian.org/ contribute patches gain access rights choose a friendly team (Games Team, Perl maintainers, Python maintainers...) bring back Ubuntu improvements not only code patches bug reports are important, too icons,.desktop files, configuration files...

23. (2) don’t be afraid! jump in! Debian is mostly about having fun

24. (3) the NM process http://nm.debian.org/ NM = New Maintainer many questions and tasks to become a Debian developer, takes some time not a requirement to maintain packages (sponsoring works, too) but gives voting rights, direct access to Debian machines... apply now!

25. (4) too scary? try the DM process DM = Debian Maintainer lighter procedure ask your sponsor about it join the debian-mentors mailing-list

26. (5) a few tips Debian is not a company if people make you feel otherwise, they’re wrong you don’t get kicked out when you make a mistake Debian is not a rock star band no need to send a resume, only your contributions matter Debian does have old, grumpy people but we are 1,000: just talk to someone else!

27. (6) now you are ready to join REAL LIVE DEVELOPERS! NOT ACTORS!

28. (7) my plans for the future seduce more people an official status for artists, translators and the like attract Ubuntu contributors, too a Debian marketing structure generalise the Debian desktop initiative better cooperation with the outside collaboration tools do not forget other distributions

29. Summary Debian is well-established and successful but the competition is intense Debian cannot just sit back and watch we need you! there is plenty of work and fun for you!
